I've posted about Tucker being aggressive before and I think it might apply a bit here as this situation is VERY 'close to home'. I am VERY careful with my dog knowing his tendancies. However, there is the rare occasion where he ends up tangled with another dog who pops around a corner or gets uncomfortably close to a person and there is a risk of that person getting bit. Tucker HAS bitten. He's bitten MANY people as a matter of fact. Noone is perfect and I really feel like I do a great job in avoiding these situations and managing my dog's contact with others.
The simply fact is that even when you are there, and when you are taking what you feel is EVERY precaution, stuff happens that is beyond your control. I learn a new lesson with Tucker every day. Owning a B, especially a B that has been in and out of fosters, moved, abused, etc is almost like a second job. I can't let my guard down for one second with Tucker. I even considered, for a brief period in heavy frustration (peeing everywhere, shredding duvets, general bad behavior), giving him back to BRAT for rehoming and I have had experience with B's in my past. In the end, however, the rewards of having him in my life far outweighed how I would feel now were he not here. There was just an adjustment period that I know fully understand. Now, I leave him alone in my condo with full access. We've reached that 'mutual respect' level and he never disappoints me because I never let him down. It seems to be exactly what my B needed in his life. Someone to take him in, struggle through the adjustments to his FIFTH home where others apparently couldn't, protect him, take care of him and treat him with respect and let him be a B.
One realizes how important their pet is when they are almost hit by a car (last night) and they yank their dog out from in front of the car (that ran a stop sign) before jumping to safety themselves.
In my opinion, he couldn't be a more perfect dog.
